All along of industry of spin printing and dyeing is traditional infection large family of China, produce a large number of liquid waste, waste gas every year, waste gas of industry of spin printing and dyeing also is ' contribution ' the large family of PM2.5, but enough attention did not get since all along. Course of study of printing and dyeing abandons spin of prevention and cure to still need to accuse formulate to publish relevant policy, accelerate spin off-gas treatment to follow research and development of the technology that monitor at the same time.

Waste gas of spin printing and dyeing basically comes from two link. Polyester fibber is dispersive in the craft of hot frit coloring of dye, high temperature brings about the dye sublimate of a few young members to come out for exhaust emission. Of cotton fabric avoid very hot, flame retardant arrange should pass bake link, you Wutian added a few chemical auxiliary, the aldehyde such as formaldehyde can appear when bake kind the phenomenon that gas releases with ammoniac gas.

It is with the filature craft of viscose fiber chemical fibber exemple, need makes raw material filature juice first, and need to join a large number of 2 vulcanization carbon in the experience of production filature fluid, because this filature is machined,experience can release the harmful gas material that gives priority to with sulfur of carbon of vulcanization hydrogen, 2 vulcanization, 2 oxidation. And heat finalizes the design machine processing is textile pre-treatment craft is important one annulus. When heat finalizes the design, all sorts of dye auxiliary on textile, coating auxiliary can be released, because this is final,vent-pipe road junction can have a large number of VOCs(organic volatile) release. These organic gas advocate if a few formaldehyde, much benzene kind, balmy hydrocarbon kind wait for organic gas.

Spin exhaust emission compares liquid waste more concealment, superintend harder also, because lack special, the standard of specific aim, many spin waste gas is basic and direct by exhaust canister perhaps organizes formal escape to come with notting have in atmosphere. So, must publish standard of exhaust emission of industry of spin printing and dyeing, make spin enterprise undertake waste gas affects processing, guide an enterprise to undertake manufacturing the improvement of engineering technology, control this industry effectively to be opposite the infection of atmosphere environment, improve the ambient air quality of parcel area. And sheet relies on to discharge a standard to prevent and cure to be returned far insufficient, spin enterprise certainly will should enlarge waste gas to administer technical research and development, improve relevant production equipment to follow craft, discharge in order to reduce what atmosphere catchs thing.
